| 摘 要： | 建立其交流异步电机的欧拉—拉格朗日数学模型，再以无源控制理论实现电机调速控制。为了转速反馈的准确性，加入了转速估算环节。充分利用被控系统已有的结构，直接比较给定的电磁转矩和估算的电磁转矩，运用PI闭环控制构造出转速信号。在Simulink中搭建仿真模型进行实验，仿真结果表明：此控制方法对交流异步电机速度控制具有较好的静/动态性能和抗干扰性。

| Abstract: | The Euler-Lagrange( EL)model of AC induction motor is established,and the speed-regulation control of motor is realized by the passivity-based control theory. In order to speed the accuracy of feedback,rotating speed estimation is added. By using the structure of the controlled system,the electromagnetic torque and the estimated electromagnetic torque are compared. Rotating speed signal is constructed by the PI closed-loop control. Simulation model is built in Simulink,simulation results show that this control method has good static,dynamic and anti-interference performances for speed control of AC induction motor. |
